Can we please leave the manifest commits and pull requests out of this thread if we're not interested in the topic at hand? Cheers jpbro!

This maxversiontested attribute is just a Microsoft nuisance the same as the PtrSafe keyword, it doesn't actually do anything other than hindering you. The "10.0.18362.0" number is suggested by Microsoft and probably marks the Windows version that first introduced the UWP controls to unpackaged desktop apps via XAML Islands. For all intents and purposes it should be treated as a constant. A lower number won't let you instantiate the DesktopWindowXamlSource object, while a higher number will restrict users with older Windows versions even though your app would run just fine on their systems in all likelihood. So just hard-code this magic number in your manifest and call it a day, there are numerous other ways to test whether a specific feature is present or not on the target computers.
